We recently purchased a Dell R640 with Perc H740P Mini (Embedded) RAID controller. There are two 500GB SAS disks in RAID 1.
When we tried to install CentOS7.2 (via cdrom) from our custom image, we got the below error as it was not able to detect the hard disks.
And from this link (https://www.centos.org/forums/viewtopic.php?t=64039), we found that it could be an issue with CentOS 7.2 and it's fixed in CentOS 7.4.
So, I downloaded CentOS 7.4 and when I tried to install it, its giving me the below error. FWIW, the same iso image is working fine on a virtual machine.
I looked around but couldn't find anything amiss. I did try re-creating the virtual drive/running hardware diagnostics but nothing helped. PERC firmware is up to date.
Any pointers will be helpful.
Let me know if you have any queries, thanks.
